Well Pump Pressure Switch 230V 1-Phase for Home Use

Spare part suitable for most domestic water installations at 230V. Includes a mechanical pressure switch designed for use with domestic water systems, expansion tanks, or garden water pumps. AC pressure switch with continuously adjustable switch-on and switch-off pressures. Single-phase pressure switch that simultaneously controls phase and neutral. Automatically activates the pump based on water pressure levels. When system pressure drops below the set cut-in point, the pump starts and stops once the desired pressure is restored. Pressure switch adjustment instructions: 1. Loosen the differential nut (2) 2. Adjust the start pressure (1) 3. Tighten the differential screw (2) to set the stop pressure For pumps exceeding 1.1 kW, an external contactor or standard power relay must be installed upstream. Three-phase 380/400V pumps require a compatible 380V power connection.
